Abstract
Предлагается преобразователь для генерирования и улавливания механических колебаний, содержащий центральное тело (4), подвешенный в пьезоэлектрической и упругой подвеске (3), находящейся в окружающей рамке (2). Подвеска (3) разделена на сектора и имеет отдельные проводники сигналов для каждого соответствующего сектора (5). Таким образом, с различных секторов (5) возможно одновременное распространение и прием колебаний. Кроме того, центральное тело (4) само может быть оснащено пьезоэлементами.Международная заявка была опубликована вместе с отчетом о международном поиске.
